（1）使用合理(li)的(de)夾(jia)緊(jin)方法和固定裝(zhuang)置

目(mu)的(de)均勻(yun)(yun)加熱和冷卻工件(jian)以(yi)減(jian)少不均勻(yun)(yun)的(de)熱應力和不均勻(yun)(yun)的(de)組織應力以(yi)減(jian)少變形。夾緊方法(fa)可(ke)以(yi)改變。圓盤部件(jian)垂直于油面，軸部件(jian)垂直安裝。使用(yong)補償墊圈和支撐墊圈。 ，花鍵孔部件(jian)可(ke)使用(yong)滲碳芯軸，疊加墊圈等(deng)。

（2）加工

當熱(re)處(chu)理(li)(li)(li)是工(gong)(gong)(gong)(gong)(gong)件(jian)加(jia)工(gong)(gong)(gong)(gong)(gong)過程的(de)最后(hou)(hou)一(yi)步時，熱(re)處(chu)理(li)(li)(li)變(bian)(bian)(bian)形(xing)(xing)的(de)允許值應滿足圖紙上指(zhi)定的(de)工(gong)(gong)(gong)(gong)(gong)件(jian)尺(chi)寸(cun)(cun)，變(bian)(bian)(bian)形(xing)(xing)變(bian)(bian)(bian)量(liang)(liang)應根據(ju)前(qian)(qian)(qian)一(yi)加(jia)工(gong)(gong)(gong)(gong)(gong)的(de)尺(chi)寸(cun)(cun)確(que)定。因(yin)(yin)(yin)此，根據(ju)工(gong)(gong)(gong)(gong)(gong)件(jian)的(de)變(bian)(bian)(bian)形(xing)(xing)，應在熱(re)處(chu)理(li)(li)(li)之(zhi)前(qian)(qian)(qian)進行尺(chi)寸(cun)(cun)的(de)預校(xiao)正，以使(shi)(shi)熱(re)處(chu)理(li)(li)(li)變(bian)(bian)(bian)形(xing)(xing)在合格(ge)范圍內。當熱(re)處(chu)理(li)(li)(li)是中間過程時，應將熱(re)處(chu)理(li)(li)(li)前(qian)(qian)(qian)的(de)加(jia)工(gong)(gong)(gong)(gong)(gong)余(yu)量(liang)(liang)視為(wei)加(jia)工(gong)(gong)(gong)(gong)(gong)余(yu)量(liang)(liang)和熱(re)處(chu)理(li)(li)(li)變(bian)(bian)(bian)形(xing)(xing)的(de)總和。通常(chang)，加(jia)工(gong)(gong)(gong)(gong)(gong)余(yu)量(liang)(liang)容(rong)易(yi)確(que)定，并且(qie)由于許多影響因(yin)(yin)(yin)素而(er)使(shi)(shi)熱(re)處(chu)理(li)(li)(li)更加(jia)復雜，因(yin)(yin)(yin)此留(liu)有足夠的(de)加(jia)工(gong)(gong)(gong)(gong)(gong)余(yu)量(liang)(liang)用于加(jia)工(gong)(gong)(gong)(gong)(gong)，其余(yu)的(de)可以用作熱(re)處(chu)理(li)(li)(li)容(rong)許變(bian)(bian)(bian)形(xing)(xing)變(bian)(bian)(bian)量(liang)(liang)。熱(re)處(chu)理(li)(li)(li)后(hou)(hou)的(de)加(jia)工(gong)(gong)(gong)(gong)(gong)后(hou)(hou)，根據(ju)工(gong)(gong)(gong)(gong)(gong)件(jian)的(de)變(bian)(bian)(bian)形(xing)(xing)規律，采(cai)用抗變(bian)(bian)(bian)形(xing)(xing)和收縮端(duan)預擴孔，以提高淬火(huo)后(hou)(hou)的(de)變(bian)(bian)(bian)形(xing)(xing)合格(ge)率(lv)。

（3）使用適當的媒體

鋼熱處理廠家在(zai)確保相(xiang)同(tong)的(de)(de)硬(ying)度(du)(du)要求的(de)(de)前(qian)提(ti)下(xia)，嘗試使(shi)用油(you)性(xing)(xing)介(jie)(jie)質(zhi)(zhi)。實驗和實踐證(zheng)明，在(zai)沒(mei)有其他條(tiao)件的(de)(de)前(qian)提(ti)下(xia)，油(you)性(xing)(xing)介(jie)(jie)質(zhi)(zhi)的(de)(de)冷卻速度(du)(du)較(jiao)慢(man)，而水性(xing)(xing)介(jie)(jie)質(zhi)(zhi)的(de)(de)冷卻速度(du)(du)則相(xiang)對較(jiao)快。而且(qie)，與(yu)油(you)性(xing)(xing)介(jie)(jie)質(zhi)(zhi)相(xiang)比，水溫變化對水性(xing)(xing)介(jie)(jie)質(zhi)(zhi)的(de)(de)冷卻特性(xing)(xing)影響更大。在(zai)相(xiang)同(tong)的(de)(de)熱處理(li)條(tiao)件下(xia)，與(yu)水性(xing)(xing)介(jie)(jie)質(zhi)(zhi)相(xiang)比，淬火后油(you)性(xing)(xing)介(jie)(jie)質(zhi)(zhi)的(de)(de)變形量(liang)相(xiang)對較(jiao)小。

鋼熱處理廠家可(ke)(ke)以改(gai)善工件的機械性(xing)能，并提高(gao)工件的強(qiang)度和硬度，但不可(ke)(ke)避免地產(chan)生變形(xing)效果。現階段，我們必(bi)須(xu)重(zhong)視中國熱處(chu)理技(ji)術和設(she)備的改(gai)進(jin)，不斷學(xue)習國外先(xian)進(jin)技(ji)術，提高(gao)熱處(chu)理工件的質(zhi)量(liang)和合格率(lv)，為中國熱處(chu)理行(xing)業做出貢(gong)獻。
